problem with zstyle file-patterns

I'm having an issue with file-patterns on zstyle:

% zstyle ':completion:*:*:yes:files' file-patterns '*XXX.*'

(using "yes" as just an example)

Now when I do "yes XXX", I get:

% yes XXX<tab>
XXX-YYY.4 XXX.3

Why is it giving me XXX-YYY.4 as an option when it doesn't match the 
file-patterns, in that it doesn't have a dot after the XXX?

I've also tried 'XXX.*'and 'XXX\.*' and get the same results.

This is with zsh version 4.3.17...

TIA,
John

First problem is that this zstyle pattern is wrong.  The file-patterns
style is looked up using the context ":completion::complete:yes::"
which does not match ":completion:*:*:yes:files".

Second problem is that even if the ":tag" part of the style were to
be used, the tag "files" is not valid.

The zle keybinding ctrl+x h (_complete_help) would have shown you this
*if* you used it *before* you executed the above zstyle command:

% yes <C-x h>
tags in context :completion::complete:yes::
    all-files  (_files _default)

Once you run the above zstyle, you've [unintentionally] created a
"files" tag, but that doesn't matter because the doc for file-patterns
says:

     The file-patterns style provides alternatives to the default tags,
     which are not used.  Its value consists of elements of the form
     `PATTERN:TAG'; each string may contain any number of such
     specifications separated by spaces.

Note that it says the default tags aren't used.  That's because you can
use file-patterns to define what the tags are, so there can't yet be any
tags at the time this zstyle is looked up.  That could be clearer (it
should probably say that *no* tags are used).

Try instead

    zstyle ':completion:*:*:yes::' file-patterns '*XXX.*:files'

I still must be doing something wrong:

% zstyle ':completion:*:*:yes::' file-patterns '*XXX.*:files'
% yes <tab>
DIR1/    DIR2/  DIR3/     XXX-YYY.4      XXX.3

I've been using zsh for a rather long time, and it's possible I've got 
old, now-irrelevant settings.  I only found out about the new completion 
system in the past week, and am not sure what to change for that.

Argh, yes.  Not doing the compinit part was the problem.  All set now.  
Thanks!
